David Cameron has told ITV News he is "extremely relaxed" over how Conservative MPs will vote over the EU referendum debate.
"I am extremely relaxed how Conservative MPs vote for this amendment to the Queen's Speech, they're not voting against the Queen's Speech as a whole, they'll be supporting the Queen's speech and it's a very strong programme for Government."
"This Bill is quite a separate issue really of being able - all Conservative MPs - to have in their hand a Bill to show to their electors: 'This what you'll get with a Conservative Government.'
"You'll get the referendum I think it is time to have."
Cameron has pledged to back a Conservative MP's EU referendum bill, as Cable labelled the move potentially 'damaging' for the country.
114 Conservative backbenchers have voted in favour of a eurosceptic motion to amend the Queen's Speech in defiance of the Prime Minister.
David Cameron has denied he has buckled under pressure from his backbench MPs over the EU debate.
